Re: [Histonet] OCT embedding...

From:"Robyn Vazquez"

Our researchers use it to hold their specimens to extract RNA from skin
samples and seem to have no problems I believe.

Dear All,

I am currently using OCT as an embedding medium for fresh frozen
tissue. Ideally i need to cut sections from this embedded tissue, laser
dissect specific areas of interest and extract high quality RNA from the
lasered tissue for subsequent RT-PCR and microarray analysis. Does
anyone know if OCT medium degrades RNA?...if so can RNase inhibitors be
added to such solutions?

Also does the actual embedding procedure itself comprise RNA
integrity?...does anyone have a good protocol for this techniwque and
subsequent good quality RNA extraction?
